  • Patent number: 8313145
    Abstract: A fitting (10) for a vehicle seat is provided having a seat part and a backrest. The fitting includes a first fitting part (11), a second fitting part (12) in geared connection with the first fitting part (11) for a relative rolling for adjusting the inclination of the backrest between several use positions, a drive motor for driving the relative rolling, a third fitting part (74) for manually free-pivoting of the backrest into a non-use position, the third fitting part (74) being releasable locked with a detent element (75), and a first coupling element (104) and a second coupling element (105) between the third fitting part (74) and the detent element (75). The first coupling element (104) and the second coupling element (105) are inactive in the normal case and become active in the misuse case, when the third fitting part (74) is unlocked and the backrest is in the non-use position and the drive motor is moving the detent element (75) backwards.

  • Patent number: 7726743
    Abstract: A fitting (10) for a vehicle seat comprises a first fitting part (11) and a second fitting part (12), which may rotate relative to each other in a circumferential direction, and which form a disc-shaped unit; a clamping ring (13) that holds the disc-shaped unit together by engaging radially outwardly over the first fitting part (11) and by being fixed to the second fitting part (12); and a group of internal stopper elements (51, 53) which limit the relative rotation between the first fitting part (11) and the second fitting part (12). Each of the first fitting part (11) and the clamping ring (13) has at least one internal stopper element of the group of internal stopper elements (51, 53).

  • Patent number: 7571962
    Abstract: In the case of a fitting (10) for a vehicle seat, in particular for a motor vehicle seat, having a first fitting part (11), a second fitting part (12) in geared connection with the first fitting part (11), and a rotatably mounted eccentric (26, 27) driven by a driver (21, 26) to cause relative rolling between the first fitting part (11) and the second fitting part (12), the first fitting part (11) and the second fitting part (12) together form a disc-shaped unit held together by a clamping ring (51), and a third fitting part (74) can be both pivoted relative to the first fitting part (11) and locked with respect to the first fitting part (11).
